GEORGE H. WLER, OF TAUGHANNOCK FALLS, NEW YORK, ASSIGNOR TO THETAUGHANNOCK EMERY WHEEL 00., OF CORTLAND, NEW YORK.-

MOWER- KNIFE GRINDER.

SPECIFICATION forming part of Letters Patent No. 629,069, dated July 18,1899.

Application filedApril 3, 1899. Serial No. 711,494. (No model.)

To all whom it may concern:

Be it known that I, GEORGE H. FOWLER, of Tanghannock Falls, in thecounty of Tompkins, in the State of New York, have invented new anduseful Improvements in Mower-Knife Grinders, of which the follow ing,taken in connection with the accompanying drawings, is aqfull, clear,and exact description I Y My invention relates to mower knife grinders.

.My object is to improve in detail the knifegrinder mechanism shown inLetters Patent granted to me under date of February 19, 1895, No.534,447; and to that end my invention consists in the several new andnovel features of construction and operation which are hereinafterdescribed, and specifically set forth in the claims hereunto annexed.

. It is constructed as follows, reference being had to the accompanyingdrawings,in which- Figure 1 shows a side view of my knifegrinderattached to the drive-wheel of a mowing-machine, the driving-wheel beingshown in dotted lines and the knife being ground also in dotted lines.Fig. 2 is a top plan view thereof, omitting the knife and the wheel towhich it is attached. Fig. 3 is an end view of what is shown in Fig. 2,looking at it from the left. Fig. 4 is a vertical cross-section throughFig. 3, except the emery-wheel, and showing the knife-bar-rest thrownover out of the way.

Similar letters of reference indicate corre away from the under side, asshown at a, so

as to allow it to readily conform to the curvature of the driving-wheelA of the mower, and b are feet adjacent to each end, which rest upon theperiphery of said driving-wheel. These feet are also provided withperforations, so that the base may be secured to the bench, if desired.The base is also provided with latterally-extending openings b,by whichit may be secured by the bolts laterallyacross the face of thedrivingwheel when it is desired to secure it for the purpose of using itin the field. The bolts (not shown) are secured to the other end and tothe opposite face of the drivingwheel in any suitable and well-knownmanner. To the base I secure the sectional socket c, and B is a framehavinga horizontal tubular bearings at the top, an arbor d at the lowerend, and a ball (1' integral with said frame, said ball fittinginto thesocket c, and

e is a bolt passing through said socket-sec tions and said ball.

Upon the arbor d is'a handgear-wheel e,

, and mounted in said horizontal tubular bearing 0 is a shaft, one endof which carries the emery-wheel fan'dthe opposite end a pinion wheel f,adapted to engage with the wheel 6', so that by rotating the wheel 6 theemerywheel f is rotated.

Upon the frame a centrally I mount a bracket 0, substantially as shownin Figs. 3 and 4 of the drawings, at the upper end of which I hinge aknife-rest g, providing suitable means upon one side of the bracket toend h of the arm h. I can then with one hand turn the wheel which by theintermediate gearing rotates theemery-wheel,and hold the knife inposition to be ground with the other hand. When the knives are grounddown to the onesv which are adjacent to the shoe or knife-head, I thenthrow the rest g over in the position shown in Fig. 4,which affords arecess a and allows the shoe upon the knife to pass into it, and thusallow me to sharpenall of the knives. It will also be observed that bythe construction set forth the emery-wheel is mounted upon a joint,which permits of its lateral movement, and with one end of the knifebearing on the rest g and the other end resting upon the swinging arm hIam enabled to readily move in either direction the knife, so as toadjust itself to the face of the emery-wheel.

What I claim as my invention, and desire to' secure by Letters Patent,is-

1. In a machine of the class described, a

base having means for secnringitin position,

a bracket mounted on said base, and having a knife-rest hinged thereto,as set forth.

2. In a machine of the class described, a base having means for securingit in position, a frame connected thereto, an emery-Wheel mounted insaid frame, means for rotating it,

a bracket mounted on said base and having a knife-rest hinged thereto,and a swinging arm secured to either end of the base, as set forth.

In Witness whereof I have hereunto set my hand this 24th day of March,1899.

- GEORGE H. FOWLER.
